v UNITED STATES PATENT OFFICE.

DAVID A. ROSS, OF CINCINNATI, OHIO.

IMPROVEMENT IN FIRE-PLACES.

Specification forming part of Lettersv Patent No. 39,836, datedSeptember 8, 1863.

To aZZ whom t may concern:

Be it known that I, DAVID A. Ross, of Ciufcinnati, Hamilton county,Ohio, have invented a new and useful Improvement in Fire-Places andStoves; and I hereby declare the following to be a full and exactdescription ofthe same, reference bein ghad to the accompanyingdrawings, making part of this specication, in which drawings like iguresrepresent like parts of the apparatus.

My invention consists in placing a rotating, curved, or ogee back in anordinary tire-place, by which means a greater amount of heat is throwninto the apartment to be warmed and a large proportion ot the fuel issaved.

The manner in which I make this application will appear more clearly byreference to the accompanying drawings.

Figure l is a perspective, Fig. 2 a front, and Fig. 3 a sectional side,view of a tire-place and grate with my improvement attached.

A is an ordinary grate, set in the usual way. B is my ogee rotatingback, resting and rotating upon theJ hooks K K. This rotation is forthepurpose of enabling` it to be thrown back, as represented by .thedotted lines in Fig. 3, to i'acili ate the charging of the grate withi'uel. *As soon as this is done theback is drawn forward untilthe toprests against the front of the tire-place at M. Near the top of therotating back, andjust below the point where it touches the top of thereplace, there is an aperture, F F, for the escape of smoke and heatedgases, which is closed,

when required, by a Bap-damper, D, hinged at G, and controlled andregulated by the handle and stem E. It will be seen that the hood C anddamper D are both attached to and carried by the back B, although thehood might be attached to the front part of the fireplace. This damperis used to control the heat as well as to regulate the draft and theescape of the gaseous products of combustion. Y

The back B may be made of cast or boiler iron, lire-clay, or any othersuitable material. I prefer that it should rest upon hooks instead ofhinging it, in order that it may be raised, if necessary, to dischargeany accumulation of dirt, soot, or ashes. In order, as far as possible,to prevent such accumulations, I make a dust-flue, H H E, entering belowthe grate and coming out above the bottom of the rotating back.

The arrows show the direction of the draft.

Having thus fully described my .improvement in all its parts, what 1claim as my inven tion, and desire to secure by Letters Patent, 1s

The rotating or movable back B, in combination with the adjuster E, whenconstructed and operatin g substantially as described.

DAVID A. ROSS.
